Mashup tutorial builder

Maker and hacker communities like the hundreds of thousands of Raspberry Pi users need illustrated tools to explain tricky techniques or give introductory tutorials. Those tools can also be used to tell mashed-up stories based on other content - the huge expansion of Minecraft videos on YouTube is one example. The goal of this project is to create a tool that can grab any kind of content from a Raspberry Pi screen, allow users to edit that content with added text, voice-over or drawn annotations, and publish it via a forum in the style of www.instructables.com
